Re: '55 engine back to life! Mostly worked...

Hi,
I think I found the source of my noise. When I was reassembling the heads, I found that #1 Exhaust valve would not go in easily and was sticking a little. Took it to my machine shop and they said they remedied it by removing a burr and cleaning out the valve guide. He also adjusted the installed valve stem height by grinding the stem ends as he noticed a 'large' variation between the valves.
A sticking exhaust valve would explain the frequency of the noise and the presence of so much soot on the back side of the front intake valves.

Unfortunately, while putting the engine back together (I removed some pistons to make sure all was clean), I broke the 2nd ring on one of the pistons. They sure break lot easier than I expected. Also struggling with the auto part store piston ring compressors.....

I only see a way to buy an entire set of rings. Mine are +0.30. Does it matter what brand etc to fit in my new Egge pistons? I can get a whole set at Egge for $45 with shipping and I see other sets for sale that are NOShttps://www.ebay.com/itm/1955-1956-PACKARD-5560-5660-1956-STUDEBAKER-GOLDEN-HAWK-V8-O30-PISTON-RINGS/283122131593?fits=Make%3APackard&hash=item41eb64e289:g:nCMAAOSwA4dWFuII

Wondering if it matters as long as they are 4.030" and if I can find something at O'reillys or Autozone in stock that would be just as good???

These are listed in the parts X-ref as compatible:https://www.amazon.com/Hastings-2M139030-Piston-Ring-Set/dp/B000C3D66U

anyone have any experience with them? (or a spare ring?? :) )



thx
